Summary: Extreme flooding can threaten life and property in flood-prone areas, as well as cause damage to critical infrastructure along roadways and canals. The effective management of these areas, and appropriate design of structures along rivers and streams, relies on understanding the magnitude and frequency of floods at gaged locations, and the ability to estimate these data at ungaged streams. Peak flow analysis and development of regional regression equations to estimate peak flow frequency and magnitude for New York have not been updated using any new data collected since 1999 (Lumia, 2006). As more data and newer technology have become available there is a need to update these data. The updated regression...

Background / Problem Hurricane Irene Figure 1 shows the declared counties for Hurricane Irene (FEMA) Five to ten inches of rain from Hurricane Irene produced widespread moderate to major flooding throughout eastern New York August 28-30. Highest rainfall totals occurred in the Catskill Mountains of southeastern New York where over 18-inches of rain was reported at Maplecrest, NY. Record water-surface elevations and streamflows were recorded at 60 USGS streamgages and 2 lake/reservoirs. Provisional recurrence intervals of peak flows exceeded the 100-yr flood (1 percent annual chance flood) at 25 USGS streamgages. Provisional recurrence intervals of peak flows exceeded the 500-yr flood (0.2 percent annual chance...
